A human frontal bone from the late pleistocene of the komombo plain, upper Egypt

From October, 1962, into March, 1963, members of the Yale University Prehistoric Expedition to Nubia collected and excavated in the area around Komombo, Uppe- Egypt.1 The area is rich in prehistoric artifact., particularly those of the Upper Paleolithic, hitherto studied almost exclusively by Vignard. His theoretical formulation of three successive cultural stages (Sebilian I-III) had often been criticized but for nearly 40 years was not reinvestigated. The stimulus for further prehistoric study in the area was provided by a programme of conversion of the land to agricultural use, which involved much levelling and ditching, and which was effectively destroying all evidences of prehistory.
